Gateway Mining Extends Haflinger Gold Strike to 4km with New High-Grade Lodes

Haflinger Prospect Expands with Significant Southward Extensions

Gateway Mining Limited (ASX:GML) has pushed the boundaries of gold mineralisation at its Haflinger prospect within the Yandal Gold Project, now tracing oxide gold over a 4km strike along the Celia Shear structure. Recent aircore drilling has delivered high-grade intercepts, including 12m at 1.1g/t Au from 104m and 8m at 1.1g/t Au from 96m, extending mineralisation 220 metres further south than previously known. These results confirm the continuity of high-grade lodes and highlight the prospect’s growing significance in the region.

Notably, the mineralisation at Haflinger is disrupted by a northeast-trending brittle structure, with drillhole MPAC0314 intersecting shallow, high-grade gold mineralisation offset by this fault. Combined with earlier results such as 64m at 1.2g/t Au including 24m at 2.4g/t Au, the data suggest multiple stacked lodes within the shear zones, underscoring the prospect’s complexity and potential.

Primary Gold Potential Emerging at Hummer Prospect

Meanwhile, the Hummer prospect, situated on a splay off the Celia Shear, is revealing promising primary gold mineralisation over a 200m strike within a broader 700m oxide zone. Aircore holes MPAC0421 and MPAC0455 ended in high-grade gold mineralisation, with intercepts of 6m at 2.2g/t Au and 5m at 1.7g/t Au respectively, confirming a coherent lode open at depth. This fresh rock mineralisation remains largely untested, with follow-up reverse circulation (RC) drilling planned to delineate the plunge and geometry of these lodes.

Gateway’s systematic exploration approach is rapidly shaping what CEO Richard Pugh describes as a "textbook structural setting" for a new gold camp, with multiple prospects including Haflinger, Hummer, Rubicon, Mustang, Colt, and Pony clustered along rotated and converging shear zones. The geological setup mirrors classic mesothermal gold systems found across the Yilgarn Craton, offering a compelling target for further drilling.

Strong Financial Position Supports Aggressive 2026 Exploration

Gateway enters 2026 well capitalised, holding $15.7 million in cash and $5.6 million in liquid ASX securities at the end of March. This financial strength positions the company to accelerate RC drilling across its key prospects, aiming to test for multiple stacked, plunging mineralised lodes and extensions along the Celia-Mustang structural corridor. The company’s recent aircore results provide a robust foundation for these next steps.

Additionally, drilling at the Great Western prospect is progressing, with initial assay results expected shortly, adding another layer of potential to Gateway’s portfolio. This complements the company’s discovery and expansion efforts at Yandal, which have been steadily building momentum over recent months.

The recent expansion of Haflinger’s strike and the confirmation of primary mineralisation at Hummer follow earlier discoveries including the new Rubicon prospect, which was highlighted in March for its significant gold intercepts over a 700m strike and untested fresh rock mineralisation. These developments collectively suggest Gateway is uncovering a substantial new gold camp in a region historically underexplored north of the Horse Well Gold Camp, where only Mustang was previously known.

Gateway’s approach reflects a methodical progression from initial aircore drilling to targeted RC follow-up, designed to unlock the full potential of the Celia-Mustang shear structures. The company’s ability to maintain a strong cash position while delivering consistent exploration results is noteworthy in the current market environment, providing flexibility to pursue multiple targets simultaneously.

With the bulk of drilling to date shallow and primary mineralisation largely untested at depth, the upcoming RC campaigns will be critical in defining the resource potential and continuity of these high-grade lodes. Investors will be watching closely as Gateway moves from discovery to delineation phases, with the potential to materially enhance the value proposition of the Yandal Gold Project.

These latest results build on the company’s recent assay releases and market activity, including a surge linked to independent research and pending assay results from the Mustang-Pony trend, highlighting a period of intense exploration and news flow for Gateway Mining. The company’s ability to convert these promising drill results into a coherent resource base will be the key to sustaining market interest.
